This Roto Grip Gem has been fully plugged using Motiv HD Ball Plug. It's then put through our Jayhawk Detox Machine to remove lane oil from the coverstock, and then finished back to box finish using one of our Storm Surface Factory Pro's. In all £55.00 of additional value included within the price. Incredible Ballistic Value!!!
Roto Grip's newest release to the HP4 line is here. The Gem features MicroTrax Solid reactive coverstock finished at 2000-grit sanded. Don't let the name fool you. This monster will power through medium to heavy lane conditions with ease.
Inside, the Defiant LRG asymmetric core will produce an overall strong hook from start to finish. This high flaring motion will provide continuation for nearly every bowler.
